Importable Xron
by Peter Bengtsson 09 Aug '00

09 Aug '00

I want to use the Xron product but I don't understand how to use it. (http://www.zope.org/Members/lstaffor/Xron/) All this Zope Zen jargon makes me dissy. What I don't understand is where and why to put reschedules at certain places. Subclasses and DTML Methods...etc. Can you please include a importable zexp on the download page of Xron. I want to do one single simple thing for now. Send the <dtml-var webmaster> constant information about various site stats. These should be sent weekly or hourly or monthly. I also want to have more than one instance of Xron. Can somebody give me examples. Especially how you set the date and time. (I have no experience of cron and I live in GMT+0) Grateful, Peter Peter Bengtsson - OD Consultancy

In some weird cases, however, this might not be the case, e.g. if "squishdot" would not be derived from "Acquisition.Implicit". Dieter

At my largest client I have a single Apache server which is front ending probably close to a dozen differenct web server serives running on various classes of machines. Quite a few of them are just linked with their normal URLs, but others are routed through Apaches proxy functions. Let's say that the main site is www.foo.bar as you suggested and you have Zope running under www.foo.bar:8080. If you had a directory under Zope that you wanted to serve called zoot, the normal URL of course would be www.foo.bar:8080/zoot. With the proxy functions you can redirect the URL www.foo.bar/zoot to point to www.foo.bar:8080/zoot and your end users are non-the-wiser for it. Is there a performance hit? Yes, a little. The sites that I work on under this arrangement are not high traffic sites by any stretch of the imagination, but they do serve important information to a select group. This allows us to have what looks like a seemless environment even though it is a function of Zope/Apache/IIS(ugh!!)/DominoGo/AlkalineSearch/WebFocus and other servers. Hope this helps.

Zope version 2.1.6 on redhat 6.2 using apache integration zia zope.cgi I have created the cdclass example in the zope developer guide on zope.org. I have created a dtml document in the cdclass zclass with <dtml-var id> and <dtml-var title> statements in it. The zclass instance is called mycd. When I try to view the instance called mycd. i get zope error "You are not authorized to access title_or_id. " I made sure all permissions for anonymouse are set to view. What could I be missing. Thanks for your help. cj technology(a)mylinuxisp.com

Permission
by Tom Deprez 09 Aug '00

09 Aug '00

Hi, I have this q'n already a long time in my head and I still don't know the answer to it. It has to do with the security-view. I hope that someone can shed a light on my brains. Why is their an Acquire permission (referred to as acq_perm in following text) checkbox column? In order to change a permission for a certain role, we have to check or uncheck this permission at the roles permission checkbox. However, for this to work we have to uncheck the acq_perm column (because if this one is checked, the permission is taken from parent-folder-objects anyway, the value of the role checkbox doesn't counts at that moment). As a drawback, this means that all roles have to be checked/unchecked, because they don't acquire the permission anymore from one of its parents-folder-objects. Now, why couldn't this be implemented like the following? Isn't this easier to grasp? The Acq_perm column doesn't exists. Assume that acquisition of a permission is always Active. The checkboxes of the role show their actual value (according to the acquisition). Thus if permissionA is checked in the parent-object, permissionA is also checked. If you want, for a certain role that this permission is not given, you uncheck permissionA. The subobject will show an unchecked permissionA box (because it acquires from its parent). In order to give the subobject again the permission, we only have to check permissionA. A) In the first approach we've to uncheck the acq_perm checkbox and have to set the checkbox of every role according to how we want the permission to be handled by that role. B) In the second approach we've to uncheck the permission checkbox of the role(s). Other roles are not effected. Am I missing something here? Is my explenation somewhere wrong? Why does Zope uses the first approach? Which, sounds for me, a little bit more complicated. Thanks for any explanation! Tom Deprez.

A Newbie question
by Hassan Aurag 09 Aug '00

Hi, I have seen on the howtos how to let apache serve static pages, but I still haven't seen an answer to the following question: Suppose I already have a big site that uses perl/cshell. Now suppose I want to move to Zope but without loosing any of that site or even converting. What would the best solution be? Example: www.foo.bar is a huge site. I want to move to Zope but wish to keep the site as is, only add zope objects with time. In other words, 90% of the site will stay static as is for a long time. How would you start this thing?
